Inject Entities using Mbox for Produc Rec.

Hi @luca_lattarini 

I think you're looking to implement Recommendations for product page is this understanding correct? 

If so, then yes it's possible to inject multiple entities to targetPageParams function.

If you pass all parameters on the page, you can quickly make updates by updating the page. 

On a product page, you might want to recommend specific items, or items with a particular price or inventory level. For a product page, you might need to set up frequently changing attributes (such as value and inventory), in addition to the keys required for a category page.

Recommendations require an at.js reference on the page.

For example, you can use the following code in the header section of your product pages:

function targetPageParams() { 
   return { 
      "entity": { 
         "id": "37895", 
         "categoryId": "My Category", 
         "value": 100.56, 
         "inventory": 399 
      } 
   } 
}

Hope this helps. Thanks
